Re: Canon EOS 550D
i just got this camera, so i think i know what your problem is.
1. make sure the aperture is as wide open as possible (f/3.5 if you're zoomed out or f/5.6 if you're zoomed in)
2. keep the iso as low as possible
3. compensate with the shutter speed until you get a good brightness.
if you need 10 seconds to take one picture it could be because your aperture wasn't open very wide (at like f/22). or it could be because the iso is too low for the lighting conditions.
